Answer:
100 g of water has the highest number of moles
Explanation:
Recall that the number of moles is obtained as given mass/formula weight
For HCl;
number of moles = 100g/36.5g/mol = 2.7 moles
For H2O;
number of moles = 100g/18g/mol = 5.5 moles
For MgCO3
number of moles = 100g/84.3 g/mol = 1.2 moles
For AlCl3
number of moles = 100g/133.3g/mol = 0.75 moles
For NaCl
number of moles = 100g/58.4 g/mol = 1.7 moles
Answer:
174.402 Torr is the partial pressure of oxygen gas.
Explanation:
According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.
where,
= Total pressure
= partial pressure of gas-1
= partial pressure of gas-2
= partial pressure of gas-3
= partial pressure of nth gas in the mixture
We have:
Now put all the given values is expression, we get the partial pressure of the gas.
174.402 Torr is the partial pressure of oxygen gas.
The angle of incoming sunlight varies at different places.

Answer:
Explanation:
Hello!
In this case, for the undergoing chemical reaction at equilibrium:
Which means that pressure-based equilibrium constant is computed via the following equilibrium expression:
Thus, by plugging in the given pressures at equilibrium, the required Kp turns out:
Best regards!
